Sync for YNAB automatically syncs transactions from over 15 UK banks + CSVs of any format to YNAB. People simply connect their bank account, and we do the rest.
We launched over a month ago, and the response has been really good so far. We have over 50 bank connections so far, and that is growing every single day.
There is a huge amount of room for this to grow into other markets outside of the UK, with most of Europe being unable to automatically import into YNAB currently.
